Surfactant-Enhanced Enzymatic Hydrolysis of Eucalyptus Kraft Pulp: The Interrelationship Between Lignin Reduction and Sugar Recovery

Catalysts, Journal Year: 2025, Volume and Issue: 15(1), P. 47 - 47

Published: Jan. 7, 2025

This study examines the effect of surfactant-enhanced enzymatic hydrolysis on eucalyptus Kraft pulps produced under high (CPHA) and mild (CPMA) alkali conditions to optimize saccharification sugar yield. Compositional analysis revealed an increase in glucan content, from 40% untreated 70.1% CPHA. Both were hydrolyzed using Cellic® CTec3 HS enzyme (Novozymes). A 22 factorial design maximum conversion (~100%) with loading 10 FPU/g carbohydrate 10% (w/v) solids. Tween 20 significantly boosted CPMA, increasing reducing sugars 42 g/L 65 efficiency 59.6% 92.2% within 6 h. By contrast, 80 PEG 400 showed limited effects CPMA. Surfactants mitigated lignin–enzyme interactions, especially as higher lignin content restricted efficiency. Phenolic hydrolysates that increased release inhibitory compounds, while kept phenolic levels lower. Overall, improved yields even moderate removal during kraft pretreatment, highlighting its potential reduce costs industrial biorefineries. underscores importance optimizing surfactant selection based biomass composition for effective cellulosic recovery.

Integrating DES Pretreatment and Enzymatic Saccharification for Napier Grass Valorization

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 18, 2025

Napier grass, a promising energy crop, offers significant potential for bioethanol production due to its high lignocellulosic content, rapid growth, and wide availability. This study investigates the use of deep eutectic solvents (DES) pretreatment, focusing on choline chloride: sorbitol (ChCl: S), ethylene glycol: citric acid (EG: CA), CA). The employs optimization pretreatment parameters with ChCl: S, including reaction time (0.5 5 h), solid-to-liquid (S/L) (1:5 1:20 w/w) ratio, temperature (90 130°C), enhance delignification, polysaccharide recovery, yield. Comprehensive biomass characterisation before after was performed. At optimum conditions 90°C, 2.75 h 1:5 S/L results demonstrated delignification hemicellulose removal increased cellulose enrichment, particularly S. Subsequent enzymatic hydrolysis fermentation yielded higher sugar recovery ethanol compared untreated biomass. highest glucose concentration obtained 5.19 mg/ml pretreated EG: CA. In addition, maximum conversion yield attained 38.43% highlights novel application these DES formulations grass provides critical insights into their mechanisms efficacy. findings contribute developing sustainable cost-effective biorefinery processes, paving way improved from non-food resources while addressing environmental economic challenges.
